Templar Traitor by Angus Donald

28 August 2025 By Editor

Buy Templar Traitor by Angus Donald

In July, 1241, Western Europe cowers in terror before the threat of a Mongol invasion.

The swift cavalry columns of Genghis Khan have smashed the steel-clad warriors of Russia, Poland and Hungary – and now Austria lies directly in their path.

At a skirmish outside the walls of Vienna, German knights capture a squad of Mongol scouts and are astonished to discover one of their number is an Englishman – a former Templar – who has been riding with these Devil’s horsemen for more than 20 years.

Interrogator Father Ivo of Narbonne is summoned to draw the truth from the prisoner before his impending trial, to find out why he abandoned his faith, his Brethren and his homeland to become… a traitor to Christendom.

Templar Traitor by Angus Donald is published on 28 August, 2025. It’s the first in his new Mongol Knight series.

Read Angus’s feature about how he came across the extraordinary true story that inspired his book.
